ANSWER:
Through an "uplift under the Earth's crust" at a "divergent boundary" a fault is formed.
Step-by-step explanation:
- Fault is the cracks or fractures formed in the land area due to the movement of rock mass.
- So, when a earth’s crust uplifts at a divergent boundary then the cracks and discontinuity of volume in the land occurs which is called as the fault.
- The active fault is the reason for earthquakes in most of the cases.
